Hy!
I have an Android project with a cpp file that needs to be compiled. This file is including some headers of the OpenCV library. The OpenCV source files are under jni/include/opencv2 folder as you can see in Android.mk file. When I try to compile with the ndk-build the file the compiler gives the following error:
"undefined reference to"
It seems that is a "error: undefined reference to" problem to all this files.
The Android.mk file have the following content:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCV_PACKAGE_DIR := $(LOCAL_PATH)/include
LOCAL_MODULE := iqindex
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(OPENCV_PACKAGE_DIR)
LOCAL_SRC_FILES := \
main.cpp
LOCAL_SHARED_LIBRARIES := iqindex
LOCAL_LDLIBS := -llog -lz
include $(BUILD_SHARED_LIBRARY)
I do not have enough experience with jni/ndk stuff and my questions are:
To compile a .cpp file that needs another header files is enough to compile it with ndk-build command and it will be all done ?
What is wrong in my attempt to compile it ? And what is wrong in Android.mk ?
EDIT: The console error is the following:

SECOND EDIT: Now the Android.mk looks like this:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# OpenCV
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
include C:/Emil/downloads/OpenCV-2.4.6-android-sdk-r2/OpenCV-2.4.6-android-sdk/sdk /native/jni/OpenCV.mk
LOCAL_MODULE := iqindex
LOCAL_SRC_FILES := \
main.cpp
LOCAL_C_INCLUDES := \
$(LOCAL_PATH)/iqindex.h
LOCAL_LDLIBS := -llog -lz
include $(BUILD_SHARED_LIBRARY)
I suppose that you forgot to add OpenCV libriries to your project. So linker can't find OpenCV related functions.
From OpenCV documentation:
If your application project doesn’t have a JNI part, just copy the
corresponding OpenCV native libs from
/sdk/native/libs/ to your
project directory to folder libs/.
In case of the application project with a JNI part, instead of manual
libraries copying you need to modify your Android.mk file: add the
following two code lines after the "include $(CLEAR_VARS)" and before
"include path_to_OpenCV-2.4.6-android-sdk/sdk/native/jni/OpenCV.mk
OPENCV_CAMERA_MODULES:=on OPENCV_INSTALL_MODULES:=on
So you should have following lines in your Android.mk:
include $(CLEAR_VARS)
# OpenCV
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
include ../../sdk/native/jni/OpenCV.mk
This is late, but in response to :
Now I have another problem: I have in the jni folder a header file named iqindex.h . The cpp file includes it, but now I have "undefined reference to" iqindex.h when I try to build. I tried the LOCAL_C_INCLUDES command in Android.mk which pointed to the header file, but then it doesn't see openCV anymore at compile time. How do I include this header to make the files to compile ?
The problem probably is that you used LOCAL_C_INCLUDES :=/foo/bar
Try LOCAL_C_INCLUDES +=/foo/bar.
You should add the include directory, not overwrite the existing includes.

I'm writing an executable for android, and in it I use std::stringstream.
Therefore, I include the library <sstream>, and when I compile my code, I get the following linker errors:

I don't know what I did wrong.. all the other STL classes worked fine until now.
Here is the project's Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_CFLAGS += -std=c++11 -w
LOCAL_MODULE := my_module
LOCAL_C_INCLUDES += \

LOCAL_STATIC_LIBRARIES := \

LOCAL_MODULE_PATH := $(TARGET_ROOT_OUT_SBIN)

Am I missing something?
I'm using NDK build & seeing this weird linker error:

I got the objdump output of fstream.o & I do see this _M_seek() function. Any ideas why it's still not able to find it. Here are some entries in my Android.mk:
LOCAL_C_INCLUDES += $(TOP)/external/stlport/stlport \

LOCAL_CFLAGS += -std=gnu++11 -std=c++11
LOCAL_CPPFLAGS := -std=gnu++11 -std=c++11
LOCAL_SHARED_LIBRARIES := libcutils liblog libutils libstlport
Am I missing anything?
See if you defined _LARGEFILE_SOURCE in your Android.mk file. If it had been defined, remove it can solve the problem.
I'm tryng to port an iOS game to Android platform with cocos2dx 2.0.4.
The core of the game is written in c++ and we managed to run it on iOS, in fact the game is avaivable on the Apple Store.
I'm using NDK r8d and lastest SDK, but I'm encountering a lot of issues when trying to build.

Any help much appreciated, thanks...
Try this in application.mk APP_STL := gnustl_static?
You get the above undefined reference error because you have not added the necessary libraries in Android.mk files. It looks something like this
LOCAL_LDLIBS := -L$(call host-path, $(LOCAL_PATH)/../../libs/$(TARGET_ARCH_ABI)) \
-lcocos2d -lGLESv1_CM -llog -lgame_logic
I am stuck with this issue even after adding the libraries. Its got something to do with setting path but I dont know how to..
If you solve this let me know

Please, Google before asking question. Here's answer:
http://answers.opencv.org/question/445/242-android-missing-nonfree-package/
I ran into same problem and found this:
http://web.guohuiwang.com/technical-notes/sift_surf_opencv_android (which after another check, is mentioned in the comments in the link above)
It is a walk-through on how to set it up so that the non-free features will be available for the NDK.
In general, the idea is to copy the header/code from the other distributions and then compile your own libnonfree.so for using these features.
I am having difficulties in my dev environment right now so I am not sure how easy it is but it seems to be updated and a good source for a solution.
(I added this answer so that it's written here on the same page as the question and people will not have to go to the other site and roll through the comments to find it)
I had been trying to solve this issue for quiet a long time,I am using a library called FreeImage and when tries to do the NDK build the code results in following error

I think you are seeing a bug in gcc/NDK that manifests itself slightly differently on Linux, Cygwin, and Windows (non Cygwin).
Here's what I did to fix it (works for Linux and for one of my developers who is blind and has to use Cygwin)...
- Remove the line that says, APP_STL := gnustl_static from your Application.mk (it's broken in the NDK; moreover, it's broken slightly differently on Linux Cygwin, Windows)
- add three lines to Andriod.mk that say,
LOCAL_C_INCLUDES := $(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/4.6/include
LOCAL_C_INCLUDES += $(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi-v7a/include
$(LOCAL_LDLIBS) += $(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi-v7a/libgnustl_static.a
^^^This line must be near the end of your $(LOCAL_LDLIBS)
The forgoing will accomplish what having, "APP_STL := gnustl_static" in your Application.mk was supposed to.
